Abstract

PURPOSE:To improve the operability, by providing a plurality of channels and making holding response through sequential changeover with one button operation. CONSTITUTION:When a subscriber SUBA is incoming to a trunk TRK0 and detected at the TRK0, the incoming call is made known with an incoming lamp and a buzzer corresponding to lines. The operator depresses the line button 0 illuminated with the incoming call lamp and transmits the trunk designation information to a switch controller SCONT. The SCONT catches the TRK0 with the trunk designation information, and connects it to the stand channel A. During the call between the operator and the SUBA, when a SUBB makes incoming call to a TRK2 and an incoming display is given on a DESK, the operator informs the holding to the SUBA, returns a line button 0, depresses the line button 2 are transmits a trunk designation information to the SCONT. The SCONT catches the TRK2 with the trunk designation information and connects it to the desk vacant channel B. In this case, at the desk, the connection information from the SCONT to the channel B is received at a relay A, automatically switchig the channel B is received at a relay A, automatically switching the channel from A to B.
